Magnetic field strength H at the centre of a Helmholtz coil | |
---|---|
$$ H_{centre}(t) = \frac{N_{each}·I (t)· 8 } {r·\sqrt{125}} \approx 0.71554·\frac{N_{each}·I}{r} $$ | (A/m) |
where: $I(t)$ - current (A) at time $t$ (s), $N_{each}$ - number of turns (unitless) of each half-coil, $r$ - radius (m) |
